I think this might be her in the 1860 census:
Pleasant Twp, Warren Co., Pennsylvania
Charles Park 29
Mary Myers 24
Fanny Myers 16
Henrietta Myers 5 months
The census date was in 14 Aug 1860, so age 5 months would place her birth about March 1860.
In the 1870 Census in Warren Borough, Warren Co, PA there is this household:
Marcia Myres, age 56, born in NY
Henrietta Myres, age 10, born in PA
Marcia Myers was also listed in the 1860 census in Warren, Warren Co., PA, married to Henry Myers, and there were household members named Cook in both 1860 and 1870.I don't know if it is the same Henrietta living with Marcia in 1870, but it seems like a good possibility.
